Construction workers were allowed to return on Wednesday morning, along with other traders, while residents went back to their homes on Tuesday evening.

Officers from 721 Explosive Ordnance Disposal (EOD) Squadron, part of 11 EOD Regiment Royal Logistics Corps, along with 101 Engineer Regiment, worked to make the scene safe.

The wartime German bomb contained 130kg of high explosives.

An Army statement said: “The troops needed to conduct a significant amount of mitigation work to prepare the site, after a 500-metre cordon had been set up, due to the amount of sensitive infrastructure in the area, particularly the A38 Aston Expressway flyover and a gas pipe.
